Image processing apparatus and method

Abstract

Provided is an image processing apparatus which includes a setting unit assigning a control block, which is a control unit of a filter process that is locally performed with respect to an image, to an initial position of the image determined based on a predetermined reference point; a movement unit moving the control block, which has been assigned to the initial position of the image by the setting unit, up to a position in which the result of the filter process is improved; and a filter processing unit performing the filter process for the respective control blocks which has been moved by the movement unit.

What is claimed is: 
     
       1. An image decoding apparatus, comprising:
 circuitry configured to
 receive encoded data generated by encoding image data including a plurality of blocks, and acquiring from a slice header of the encoded data block control data controlling whether an adaptive filter process is performed to each of the blocks if said each of the blocks is included in a slice corresponding to the slice header; 
 decode the received encoded data to generate image data; and 
 perform the adaptive filter process on the generated image data based on the acquired block control data. 
 
 
     
     
       2. An image decoding method, comprising:
 receiving encoded data generated by encoding image data including a plurality of blocks, and acquiring from a slice header the encoded data block control data controlling whether an adaptive filter process is performed to each of the blocks if said each of the blocks is included in a slice corresponding to the slice header; 
 decoding the encoded data received to generate image data; and 
 performing the adaptive filter process on the image data generated by decoding the encoded data based on the acquired block control data. 
 
     
     
       3. The image decoding apparatus according to  claim 1 , wherein the circuitry is further configured to decode the block control data together with the image. 
     
     
       4. The image decoding apparatus according to  claim 1 , wherein a slice header of each slice includes block control data corresponding to each block included in the respective slice. 
     
     
       5. The image decoding method according to  claim 2 , wherein the method further comprises decoding the block control data together with the image. 
     
     
       6. The image decoding method according to  claim 2 , wherein a slice header of each slice includes block control data corresponding to each block included in the respective slice.
